Application March 20,

1 Claim.

The invention relates to a cap construction and more especially to a receptacle closure top or cap.

The primary object of the invention is the provision of a cap of this character, wherein. the

same is especially useful in connection with a collapsible tube for containing paste or other material and hasl iiexible connection with such tube vso that the cap will not become lost when removed for the opening of the tube to dispense the contents thereof and also the said cap will be maintained or held in a position for convenient application to the tube.

Another object of the invention is the provision tion thereof with the tube for application thereto or removal therefrom is of a character having inherent flexibility so that the said cap can be swung to an applying position or to a position removed from the tube to avoid interference with the .dispensing of the contents of such tube and at the same time the cap will remain associated with the tube to avoid loss or misplacing of such cap as would be the case if it were entirely free from the tube.

A still further object of the invention is the provision of a cap of this character, which is simple in its construction, thoroughly reliable and effective in operation, easy of manipulation, strong, durable, and inexpensive to manufacture and install.

With these and other objects in View, the invention consists in the features of construction, combination and arrangements of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, `which discloses the preferred embodiment of the invention and pointed out in the claim, hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary side elevation of a collapsible tube showing the cap constructed in accordance with the invention', applied and in v closing position.

Figure 2 is a view similar to Figure l showing the cap in opening position.

Figure 3 is a top plan View with the parts in the position shown in Figure 1. I

Figure 4 is a fragmentary side elevation partly in section on an enlarged scale.

Figure 5 is a fragmentary perspective view of the eye member constituting a part of the body of the tube. 4

Figure 6 is a plan view of the inherently flexible connecting element between the body of the tube and the cap. I

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail,` A designates generally a portion of the body of a collapsible tube functioning as a container for paste or other loose material. ThisbodyA is formed with an externally threaded neck I engageable 5 by an internally threaded screw cap Ii. The cap II has an external annular groove or channel I2 peripherally thereof and engageable about this cap to be confined within the groove or channel I2 is the ring end I3 of an inherently flexible or bendable wire ill, which at the other end thereof has bent therefrom an attaching loop I5 loosely engageable with an eye i6. 'Ijhe eye I6 is an integral part of the upward tapered portion Il of the body A of the tube. I The ring end I3 loosely embraces the cap and is confined within the groove or channel l2 which is of a width to allow the cap I I to'have a limited play through said ring end I3. This pla-y enables the cap li to be screwed onto or unscrewed from the neck portion I0 of the body A of the tube.

The lug I6 is formed with a `V-shaped notch I8 therein for the seating of the loop-attaching end I5 within this notch and in this way maintaining the Wire I4 in a fixed condition at the loop-attaching end I5 engaged in said eye I6.

When thecap is to ybe attached to the neck portion Il) of the tube A, the wire lli is bent or ilexed into a position as shown in Figure 4 of the drawing, thus bringing the cap into alignment with the neck portion Ill and allowing the screwingof the cap upon the neck portion for the closing of the tube as is clearly shown in Figure l of the drawing.

When the cap is removed from the neck portion IE! of the tube A, the wire It can be bent outwardly in alateral direction to the position as shown in Figure 2 of the drawing and thus holding the cap remote from` the neck portion I0 so as not to interfere with the dispensing of the contents of the tube A, as will be clearly apparent.

What is claimed is:

A cap for collapsible tubes having a screw threaded neck, a screw threaded body adapted to engage the neck, the body being of elongated cylindrical form provided with external annular shoulders spaced from each other, a single length of inherently flexible wire formed. with a loop end snugly embracing the body between the shoulders for the rotation of said body in the loop, a perforated ear projecting from the tube at one side of the neck and having a notch in its outer edge outwardly angled with respect to the said neck, and a twisted end on said wire trained through the perforation and notch in the ear for holding fast the said twisted end of the Wire in its joinder with the ear.
